"Ford are bringing out an improved turbo-charged diesel engine and they think that I can explain whafs new about it and why ifs better than other engines.
Most trucks have had diesel engines for the last 30 years or more.
The principle Herr Rudolf Diesel introduced, when he first heard how inefficient steam engines were, was to compress the air so tight in the cylinder that its temperature was sent up to about 800°C.
This was so hot that when the fuel was injected it ignited right away without need for a sparking plug.
A further advantage was that by running the engine like this at high pressure he obtained greater efficiency.
That is to say he got more work from each unit amount of fuel. Turbo-charging, first applied to big marine diesels, uses part of the waste energy of the gases in an engine's exhaust pipe to run a little turbine.
This drives a compressor which forces more air into the engine's cylinder than would otherwise be sucked in by the pistons.
It gives three important advantages.The first is a more efficient use of fuel.
The second is particularly valuable: because more fuel is taken into each cylinder at every stroke, more power is obtained from the engine.
A third benefit is that because the turbo-charger compresses the air which flows into thE engine, this air becomes hot, the fuel that is mixed with it burns more promptly and the engine is consequently quieter.
By fitting a turbo-charger these considerable advantages are obtainei for an increase in the weight of the truck of about 100 lbs.
If the owner gets an extra 30 HP for this increase in weight (as indeed he does), he can therefore carry some tons more goods in his vehicle.
Of course to win these prizes the structure of the engine must be made stron; enough to stand the extra pressure, the cooling system must be efficient enough to dissipate the extra heat which is inevitably rejected by the engine.
This is part of the Carnot Cycle (which, I need hardly add, is not a means of transport but one of the fundamental principles of thermodynamics).
And, since the turbo-charger may at times need to spin at100,000 RPM it must obviously be properly made, adequately lubricated and precisely designed to suit the engine itis to work with.
Ford have, they say, done three things to make their Turbo II engine better than the previous model they made.
To start with, the engine has been strengthened by clamping the cylinder head down more firmly.
Next, they have taken a good deal of trouble to make sure that the cooling system works more efficiently, the thermostats do their job and the water circulates no matter what the engine is doing. Finally, improvements have been made in turbo-charger lubrication to make it easier for the men who service the trucks and keep them in good order After having heard what the Ford people had to say about their Turbo II engine I felt that I knew what they were talking about I hope that now you do too:' Those of you who are directly involved with the transport business will obviously want to know more.
